基于单片机的出租车计价器论文.rar

摘要
随着生活水平的提高,人们已不再满足于衣食住的享受,出行的舒适已受到越来越多人的关注。于是,出租车行业以低价高质的服务给人们带来了出行的享受。随着出租车行业的发展,出租车已经是城市交通的重要组成部分,但是总存在着买卖纠纷困扰着行业的发展,出租车计价器是乘客与司机双方的交易准则,它是出租车行业发展的重要标志,是出租车中最重要的工具。它关系着交易双方的利益。具有良好性能的计价器无论是对广大出租车司机朋友还是乘客来说都是很必要的。因此,汽车计价器的研究也是十分有应用价值的。而采用模拟电路和数字电路设计的计价器整体电路的规模较大,用到的器件多,造成故障率高,难调试,对于模式的切换需要用到机械开关,机械开关时间久了会造成接触不良,功能不易实现。而采用单片机进行的设计,相对来说功能强大,用较少的硬件和适当的软件相互配合可以很容易的实现设计要求,且灵活性强,可以通过软件编程来完成更多的附加功能,用数码管显示费用。针对计费模式的切换,通过软件编程就可以轻易而举的实现。避免了机械开关带来的不稳定因素。另外在本方案中那个使用了点阵的液晶,可以实现更加友好的使用界面。数据信息一目了然,并且即使是成品也可以方便的修改使用界面,更可根据不同的公司客户使用不同的局面。

ABSTRACT
With the improvement of living standards, people are no longer satisfied with the enjoyment of food, clothing and housing, fort of travel has been more and more people concern. Thus, the taxi industry to low-cost high-quality services to the people the enjoyment of the trip. As the taxi industry, taxi is the city an important part of traffic, but overall there is a dispute to plague the development of the industry is Taximeter both passengers and drivers of transactions criteria, it is the taxi industry an important indicator of development is the taxi most important tool. It relates to the interests of both parties. Has a good performance regardless of the meter is the majority of taxi drivers or friends of passengers is very necessary. Therefore, the research vehicle meter is also very valuable. The use of analog circuits and digital circuit design the whole circuit of the meter of the larger, multi-use devices, resulting in high failure rate, they are difficult to debug, the mode switch needed mechanical switch, mechanical switch will cause a long-time exposure poor function is not easy to achieve. Carried out by the use of single-chip designs, relatively powerful, with less hardware and appropriate software can easily cooperate with each other to achieve the design requirements, and flexibility, can be programmed through software plete the more additional function, the cost of digital display.
